DELTA is a synchrotron source located at the University of Dortmund, Germany, and
is operated a 1.5 GeV with a maximum electron current of 120 mA and lifetimes of
about 10 hours. The beamline BL9 is attached to a superconducting asymmetric
wiggler which supplies radiation in the energy range between 5 keV and 30 keV. The
incident radiation is monochromatized by means of a Si311 double crystal monochromator
with sagittally bend second monochromator crystal. The experimental endstation
of BL9 is equipped with a Huber six-circle diffractometer and is dedicated to (grazing
incidence) x-ray diffraction and x-ray reflectivity studies on solid surfaces and thin
films. Recently, the endstation was extended to perform small and wide angle x-ray
scattering experiments making use of a MAR345 image plate scanner. Moreover, a
spectrometerin Rowland geometry is accessible to perform resonant inelastic x-ray
scattering experiments. The different setups will be described in detail and key applications
will be presented with focus on small angle x-ray scattering, texture analysis
and reflectivity studies.
